The AA-GB selective antenna amplifier is used to amplify the receiving signal in the 580-608 MHz band from a wireless microphone (> 15dB). The antenna amplifier should be connected directly to the receiving antenna. Connect the amplifier output with a coaxial cable to the receiver’s antenna input. The AA-GB antenna amplifier compensates for losses in the TASKER RG-58CU coaxial cable up to 40mb, while the BELDEN H155 cable up to 80mb. When two amplifiers are used in series, the distance doubles. The antenna amplifier has been configured to work with the LDU-505 wireless set.
